6 Claims. (01. sci-is) My invention relates to improvements in apparatus for carbonating water for beverage purposes.

My invention has for one of its objects that of constructing a compact, quietly running, readily assembled carbonator which shall be effective in its operation, which automatically operates to maintain the supply of water constant and which shall be quiet in its operation.

For the purpose of disclosing my invention I have illustrated one embodiment in the accompanying drawings, in which:

Fig. 1 is a front elevation of a carbonator embodying my invention;

Fig. 2 is a transverse sectional view thereof,

and g Fig. 3 is a detail sectional view of the water pump. 7 Y

1n the embodiment illustrated, 1 provide a front 7 plate 1 which is preferably fairly heavy in construction and may be made of cast iron or the like, having on its rear face a liner 2 of tin or other metal which is resistant to the action of This face plate is vertically mounted upon a base 3 which base may be of stamped or cast metal and it will be noted that the plate is mounted near the front end of the base, this for counter-balancing purposes which will more fully hereinafter appear. For maintaining the plate in vertical position on the base,

I provide angle members, the vertical arms 4 of which extend parallel with the plate and are secured thereto by bolts or screws 5. These arms extend through the top of the base 3 and the horizontal arms 6 of the angle members extend beneath the base 3, being likewise bolted or otherwise secured to the base. There are two of these arms, one at each corner of the plate. The carbonator body 7, which is adapted to be attached to the rear face of the plate 1, is preferably of cylindrical shape with its rear end closed and drawn from a single sheet of metal which in itself resistant to the action of carbonated water. This metai nay be of any desired character having the characteristic above pointed out and I have found that the present commercial stainless steel is satisfactory. The forward edge of the body is provided with an annular flange 8 by which it is secured to the rear face of the plate 1. In securing the flange position I preferably interpose between the flange and the face of the plate 1 a gasket 9 and clamp the flange between this gasket 9 and a clamping ring 10, which ring is secured to the plate 1 by means of bolts 11,;

which extend through the plate, the gasket, and the flange or the ring.

Water is supplied through a spray nozzle 12 mounted on the plate 1 and extending therethrough, this nozzle having a supply opening 13 extending therethroughand having spray openings in the interior end thereof. This nozzle is screw threaded at its rear end into a sleeve 14, in turn screw threaded as at 15 onto a nipple 16, likewise surrounding-the nozzle 12 and extending through the plate 1, this nipple having a flange 17 on its inner end and a clamping nut 18 screw threaded on the. exterior of the plate. 1. The water supply nozzle is connected by a suitable connection 19 with a pump 20.

For supporting the pump as and its associated parts, I provide a plate 21 horizontally disposed and having a downwardly extending vertical web 22 bolted to the front face of the plate 1, part of the same bolts for securing the carbonator .7 in position being likewise adapted for securing the web 22 in position. Water supply pump 20 is secured against one face of an upwardly ex.-

tending bearing ear which is preferably cast integral with the platform 21. A second bearing ear 24 spaced apart from the 'ear23 extends upwardly from the platform 21 and a reciprocating yoke '25 is mounted between these bearings. This yoke is provided with supporting rods 26 and 27 supported in bearings in the cars 24 and 23 respectively and the rod 2? forms a plunger for tie water pump 29. The yoke 25 is hollow and has arrangeo therein a sliding block 28 which in turn is mounted upon a crank pin 29 extending from a disc 30. This disc is mounted upon one end of a shaft supported in ball bearings carried in bearing ears 32 and 33 extending vertically from the platform 21. eyed on this shaft 31 and between the bearings is a spiral gear 34 meshing with a worm 35 on the shaft 36 of 9, an electric motor 3'1. A suitable housing 38 surrounds the worm gear drive, which housing may contain the proper lubricant so that, the drive may operate in a bath of oil. By the above construction a reduction drive is provided between the motor and the pump plunger 27 and the rotary movement of this drive is converted into a reciprocating movement by means of the scotch yoke heretofore described.

CO2 is admitted to the carbonator at the bottom thereof through a supply pipe 39 connected with a suitable supply. It will be noted that this supply pipe enters atthe bottom. of the carbonator so that the C62 will passthrough the body of the liquid at the bottom working up through the liquid whereby'a thorough mixing of the liquid with the carbonic acid gas is accomplished. A takeoff bypass connects the supply pipe 39 the pipe 15 whereby a certain proportion of CO2 passes into the carbonator at the top thereof and comes in contact with the water spray delivered from the spray nozzle. This CO2 supply pipe 39 surrounds a water takeoff pipe 41 I ich it will be noted projects into the caroona tor, at the bottom thereof, and, beyond the CO2 supply pipe.

fhe takeoff pipe 41 is controlled by a valve 42 and is connected with the bottle filling machines or other suitable device. V

For controlling the level of the water in the carbcnator tank 7, I provide automatic m ans for shutting off the water pump when the level in. the tank reaches a predetermined point. To this end i provide a balancing bucket 43 supported by a connecting link 44 from a balancing leverd, pivoted at 45 on the web 22 and having at its opposite end a counterbalancing weight 47. 'Ifnis lever 45 is connected by a suitable adjustable connection 48 with the switch for controlling the circuit through the electric motor 37. The balancing bucket 43 receives liquid from the car bonator 7 through a takeoff connection 49 with the takeoff pipe 41 and through a flexible hose 50 which extends to the bottom of the balancing bucket. It will be noted that by this arrangement the liquid level in the balancing bucket corresponds to the liquid level in the carbonator. The top of the balancing bucket is connected by a flexible hose 51 with a connection 52 extending to the pipe 14 so that, the pressure in the balancing bucket l3 will always equal the pressure in the carbonator. By this arrangement as the liquid in the carbonator rises the liquid in the balancing bucket 43 rises until the weight of the liquid in the' balancing bucket43 overcomes the counter-balancing weight 47 whereby the bucket will drop pulling with it the end of the lever 45 and operating the switch to cut off the motor.

In order to agitate the liquid in the carbonator body during the induction of 002 to the body, I

provide an agitator in the form of a pair of paddle. 53 mounted on a rotating shaft 5 1-. This shaft extends through the plate 1 and through a stuffing box 55 to prevent leakage. The outer end of the shaft is provided with a sprocket 56 which is connected by a drive chain 57 witha sprocket 58 on the shaft 31 whereby the agitator is driven from the motor 37.

The pump for delivering water to the carbonator is an extremely simple construction and includes the cylindrical barrel 59 having in one end thereof a flapper valve 69, in the intake con nection 61. T e plunger 27 operates th ou h a stufling box 62-: at the opposite end, the entire structure being mounted on the upright ear 23.
